Swedish Pomerania

Swedish Pomerania was a dominion of Sweden that existed from 1630 to 1815, with Stralsund serving as its capital. Sweden garrisoned the city of Stralsund after seizing it from the Holy Roman Empire in 1628 during the Thirty Years' War, and Sweden was granted control of Pomerania under the 1630 Treaty of Stettin. In 1653, the Swedes gained control of western Pomerania, but the governing Swedish aristocrats refused to abolish serfdom, meaning that the Swedish aristocrats would be forced to instead become imperial princes of the Holy Roman Empire; only Stralsund was fully incorporated into Sweden. In 1679, Sweden lost most of its Pomeranian possessions east of the Oder River as a result of the Scanian War, and it lost more of Pomerania in 1720 as a result of the Great Northern War. During the Napoleonic Wars, the army of France conquered Stralsund from Sweden, which had joined the coalition against Napoleon I, and it was occupied for years. In 1814, Sweden agreed to cede Swedish Pomerania to Denmark-Norway in exchange for Norway, but Norway's declaration of independence and the start of the Swedish-Norwegian War led to Sweden simply losing Pomerania to Denmark as it struggled to conquer Norway. In 1815, however, Pomerania was granted to Prussia at the Congress of Vienna, which redrew Europe's borders to form a new order.
